A pulse generator, generator set and energy harvesting device

Abstract

The invention provides a pulse generator, a generating set, and an energy harvesting device. The pulse generator comprises a cylindrical base body whose inner side wall is formed by four inner surfaces. The angle between two adjacent inner surfaces of the base body can change under the action of external forces. The four inner surfaces are respectively provided with an electrode layer. The upper surface of each electrode layer is provided with a friction layer in a contact manner. With the action of the external forces, the four inner surfaces drive the friction layers to contact or separate in a pairwise manner. The electrode layer which is arranged contact with the friction layer can output electric signals to external circuits. Corresponding, the invention also provides a generating set comprising a plurality of the pulse generators, and an energy harvesting device applying the generator or the generating set. The generator or the generating set is simple in structure, and can convert vibration formed by pedestrian walking, expressways, and bridges, and other mechanical energy to electric energy.

Description

technical field [0001] The invention relates to the field of nano generators, in particular to pulse generators and generator sets capable of converting mechanical energy into electrical energy. Background technique [0002] Vibration mechanical energy is a widely existing form of energy, including ocean waves, engine vibration, highway, bridge and tunnel vibration when cars pass by, and human body movements such as walking, running, twisting, etc., all of which will generate vibration mechanical energy. Although vibrational mechanical energy exists widely, it is often neglected and utilized without effective means of collection, and is usually wasted. [0003] At present, the principles used by generators that convert mechanical energy into electrical energy mainly include electrostatic induction, electromagnetic induction, piezoelectric properties of special materials, and electrostatic pulse generators. However, the electrostatic induction generators that have been inven...

Problems solved by technology

However, the electrostatic induction generators that have been invented have shortcomings such as large volume and narrow applicability, while electromagnetic induction generators and piezoelectric generators generally have defects such as complex structures, special requirements for materials, and high cost.

Electrostatic pulse generators have shortcomings in miniaturization and light weight, and the output power density is small, which cannot meet the needs of various vibration mechanical energy collection
